SplitKit: Fix liveness recomputation in some remat cases.
Example situation:
```
BB0:
%0 = ...
use %0
; ...
condjump BB1
jmp BB2
BB1:
%0 = ... ; rematerialized def from above (from earlier split step)
jmp BB2
BB2:
; ...
use %0
```
%0 will have a live interval with 3 value numbers (for the BB0, BB1 and
BB2 parts). Now SplitKit tries and succeeds in rematerializing the value
number in BB2 (This only works because it is a secondary split so
SplitKit is can trace this back to a single original def).
We need to recompute all live ranges affected by a value number that we
rematerialize. The case that we missed before is that when the value
that is rematerialized is at a join (Phi VNI) then we also have to
recompute liveness for the predecessor VNIs.
